I just can not load any custom skin, every skin for me is default minecraft skins, no idea why. Even servers have the same issue. Also i noticed that when i try opening skin tab in launcher it takes some time. And while its loading i cant boot up the game itself, with error popping up (second image). When the skin tab has finally loaded it shows me that the skin of Alex is equipped, even though i didnt equip it. Even changing the skin and reopening tab with launcher doesnt help.
What should I do to fix this.
have you tried removing the 64x64 texture pack you are using?
